Abstract

Ruptured aneurysms in perforating arteries are uncommon. We report a case of a basilar perforator artery aneurysm that was treated successfully using simple stenting to induce a rectifying effect without using a coil. In this case, coiling for the aneurysm was attempted initially, but it failed because of anatomical and practical problems. After placement of two stents in the basilar artery, the aneurysm was occluded completely without any neurological deficits at 100 days after the procedure. Although superselective coil embolization is ideal even in a small perforator aneurysm, simple stenting for a parent artery is a preferable treatment, especially in challenging cases for coil embolization of the aneurysmal dome.
